I can see where zfs would be good for this...   Does this data have
some sort of life cycle where you could give the devices a small space
to write with the data periodically processed (server-side) into the
large archive?  Or could they use an http post, database write, or
some other application-level protocol instead of seeing the filesystem
directly?
